BUMPER Filed May 9. 1930 SWW/nto@ @www Patented Nov. 17, 1931 UNITEDSTATES BLADEN M. SHORYT, 0F DETROIT, MICHIGAN BUMPER Application led May9,

This invention relates to bumpers for automobiles, and has for itsprincipal object to provide a bumper of this` character comprising animpact section consisting of a plurality of vertically spaced impactbars anda rear auxiliary or reinforcing section wherein the centralportion of the front or impact secp tion will be effectivelystrengthened bythe rear section and wherein it Ywill be possible toinsert a starting crank between. the'impact bars without sacrificing thestrength oi. the bumper.

The bumper shown herein is of the general type shown in McGregor PatentNo. 1,372,- 154, issued March 22` 1921, and comprislng a front or impactsection consisting of a plurality of vertically spacedbars and connectedat their ends to the ends of a rear or auxiliary section. the centralportion of which is arched forwardly to form a trussed reinforcement forthe central portions of the front or impact bars. p Y

In the drawings Fig. l" represents a plan view of a bumper constructedin accordance with my invention, the said` view showing portions of thesupporting arms and of the means for securing the bumper thereto; Fig. 2a front elevation of the bumper shown in F ig. 1; Fig. 3 a detail insection of the bumper clamping means; Aand Fig. 4.- a detail in sectionof the bumper securing and supporting means. f

Describing the various parts by reference characters. 1 denotes `theupper and 2 the lower front or impact bars, each of the aforesaid barshaving its ends curved rear, wardly, as indicated at 1a on Fig. l, andeach provided at each end thereof with an eye, the eyes of the bar 1being indicated at lb and the eyes on the ends of the bar 2 beingindicated at 2b. l v

Cooperating with the front or impact section comprising the bars 1 and 2is a composite rear or auxiliary section, and this latter sectioncomprises a main bar 3 which is provided at each end thereof with an eye3it adapted to be interposed between the eyes lb and 2b and to beconnected therewith by means of bolts 4 and spacing washers 5. Thecentral section of the bar 3 is bent leso.f serial No. 450,905.

toward and preferably into engagement with the central portion of theupper bar 1, being deliected both Vupwardly and forwardly as shown at31?, so that the central portion of the bar 3 will register with and becovered by the central portion of the bar l.

In` addition to the bar 3, a shorter bar 6 is employed, being located atthe back of the bar 3 and being of such be clamped to the arms 7 (whicharms may be the front endsof the vehicle frame) by the clamps 8 whichsecure the bar 3 to said arms. These clamps may be of any standardconstruction, but I clamps each comprising vupper and lower members 8aand 8b having their rear ends connected to the arms 7 by bolts 9 andhaving in the front plate 8c thereof a short clamping bolt 10 adapted toagainst the end of the arms 7 Y Y This central portion of the bar 6 isdeflected forwardly and downwardly, as shown at 6LL and is preferably inengagement, with and directly behind front bar 2.

The central portions ofthe bars 1, 2, 3 and 6 are connected by means ofal front clamping plate and rear clamping plates, the front clampingrplate 11 being ot any desired form 80 which will provide an opening llafor the reception of the starting crank, while of a vertical extent tooverlap sufficiently the front surfaces of the bars 1 and 2. For a rearclamping plate. I prefer to employ a'plate 12 similar to the frontclamping plate, its upper'and lower ends overlapping to a suiiicientextent the portions 3b and 6a of the bars 3 and 6, respectively. Theclamping plates 11 'and 12a-re connected by bolts 13'carried'by the`viro'ntplate l1.

Due to the construction and arrangement of the parts shown herein, Ihave provided a bumper of the type ,comprising a front or impact sectionconsisting of spaced impact bars, and a rear auxiliary reinforcingsection, lwith simple and effective means whereby the central section ofthe bumper is strengthened and provision is made for the insertion vofthe starting crank therethrough.
